Just because you don't understand what I said doesn't make it bad economics OR bizarre math krakra.
Companies can run according to different profit principles. They can seek out a high profit per item, or they can seek out high profit through volume. Increasing volume of items sold by adding an extra 2% to your customer base can help to offset and even recover the costs a company accrues in order to obtain that extra 2%.
Karrie, where in that does the consumer get the break?
